Wiltshire

Knocking through to a rear extension in Wiltshire

Steel beams, padstones and props to open the back of the house safely. We design and build rear extensions across Wiltshire, from Swindon and Salisbury to Trowbridge, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.

Older houses in Wiltshire often have solid brick back walls carrying a lot of weight, so the steel design comes early. Stone-built and rendered houses are common around Wiltshire, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.

What does it cost in Wiltshire?

As a guide, £3,500–£9,000 including VAT. We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.

What approvals does it need in Wiltshire?

Every rear extension in England needs Building Regulations approval, whether or not planning is needed. You can use the council's building control service or a registered building control approver, by full plans (checked before work, usually within five weeks) or a building notice, and you get a completion certificate at the end.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ

Questions people ask

Can the whole back wall come out?

Often, with a beam across the full width or a goalpost frame. Some walls need a short pier left at the ends.

Do I need building control for a beam?

Yes. The calculations and the installed steel are checked.

How long does it take?

The wall itself usually comes out in a day or two, timed for when the extension is weathertight.

Do you cover all of Wiltshire?

We cover 14 towns and districts in Wiltshire, including Swindon, Salisbury and Trowbridge.

Who builds the extension?

Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
